Hi Alexis,

bzgl. CD300 war genau diese Frage vor einiger Zeit auf Beechtalk.

George Braly (GAMI) himself gab darauf folgende Antwort:

"Cirrus tried to make it work.

LOTs of problems - - HEAVY. Results in a huge c.g. issue. Required a re-design of the nose gear to support it.

Then some of those "unexpected problems ". Torsional vibration. Redesign of the entire firewall required.

Starting problems. . . and the engine (with turbochargers) does NOT make rated power above about 12K feet. So at more than 12,000 feet the (available) power to weight ratio drops dramatically below that of a turbocharged Continental or Lycoming engine.

Oh... did I mention "re-start" problems at altitude.

And the beat goes on . . . and the beat goes on..."
